This has happened twice so far... Installed a fresh copy of Centos 5.2 (64bit) on an ESX Server VM. Installed Plesk 9 for Linux. System behaved beautifully. The next day I try to log in via the webadmin (8443). Instead of getting the login screen, I am given a page (in firefox - ie gives no useful info) that says the current page is causing a redirect loop. I can not log in at all. I have tried nuking and reinstalling, but after several hours of working properly, the redirect loop error pops up again. Any ideas???
